Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of geotechnical engineering, especially to a kind of fast pouring reinforced concrete pile model. BACKGROUND

[0002] Model test is an effective method to evaluate the stress and deformation state of reinforced concrete pile in engineering application, which can conduct mechanical property test and study durability problems such as reinforcement corrosion. However, for pouring reinforced concrete pile model, the existing technology usually adopts non-casing pouring method, which has many technical challenges.

[0003] Traditional non-casing pouring method often faces limited number of cycles, poor fixation, easy displacement, easy blockage and uneven pouring, etc. Especially within a few hours after pouring concrete (before concrete is completely dry), the casing must be removed in time. Otherwise, it is difficult to remove the casing after the concrete is completely dry, which will seriously affect the quality of the concrete and may lead to distortion of the final test results.

[0004] To solve these problems, the present application introduces an innovative multi-casing pouring concrete method. By pouring multiple concrete piles at the same time, this method not only ensures the uniformity of pile quality during pouring, but also significantly improves construction efficiency. At the same time, the optimized casing design and construction process make it easy to remove the casing at the appropriate time point, which not only ensures the uniformity and quality of the concrete, but also facilitates the accuracy and reliability of the experimental results.

[0005] Therefore, this innovative pouring technology not only applies to practical application in engineering construction, but also provides strong support for scientific research and technical exploration in related fields, promoting the further development and application of reinforced concrete pile model test.

[0031] The working steps of the device are as follows:

[0032] The first step is to cut the steel wire into a steel wire segment with a required length and to wind the steel pipe for one turn to fix the shape; when binding, the longitudinal reinforcement is passed through the drill hole on the round wood piece 4, and the round wood piece 4 is arranged at the upper part and the bottom part of the longitudinal reinforcement to fix the head and tail; because the bending stiffness of the steel bar 2 used in the test is too small, it is difficult to fix, therefore, an additional round wood piece 4 is needed to be placed in the middle, and the stirrup 3 is bound from top to bottom at the round wood piece 4; the PVC sleeve pipe 1 is cut into two halves along the longitudinal direction, and mineral lubricating oil is applied on the inner wall; before pouring concrete, the two halves of the PVC pipe are spliced together, the waterproof insulation tape is sealed at the cutting seam to prevent water leakage, and the reinforcing sleeve ring 5 is arranged at the outer periphery of the PVC pipe at intervals to fix the mold; the drill wood piece with the same diameter as the inner diameter of the PVC pipe is arranged at the upper and lower ends to position the steel bar 2 cage;

[0033] The second step is to solve the problem that mortar leakage is easily caused if the waterproof treatment is not good due to the large gap between the bottom wood piece and the PVC pipe wall; the specific method is as follows: the butyl high-pressure waterproof self-adhesive tape is cut into appropriate length sections, each section is stretched and then adhered to the PVC pipe wall in the clockwise direction, a layer of PVC insulation tape is wrapped on the surface after slight pressing to protect it, the waterproof self-adhesive tape is cheap and safe to use, and the tape itself does not have adhesion, but high adhesion is generated between the tapes after stretching and extrusion, forming an effective waterproof film with good sealing performance;

[0034] The third step is that when pouring the model pile, the vibrator is used to vibrate the pipe wall closely after pouring a certain amount of concrete to ensure that the bubbles in the concrete are discharged; after pouring is completed, the vibrator is used to vibrate up and down to avoid uneven pouring, and finally the concrete on the pile top is smoothed; the removal process is as follows: after the concrete pouring is completed, the device is placed in a cool place for two days, and the concrete pile strength is preliminarily formed before demolding; after the reinforcing sleeve ring 5 and the waterproof insulation tape are removed, the PVC pipe breakage is lightly tapped using a soft hammer until it is slightly cracked, and then the two PVC pipe molds and the positioning drill wood pieces are taken out in sequence.
